Slide valve type DBS

 
For sealing and dosing of bulk materials and granulates - The slide valve is equipped with two replaceable stainless steel flanges. All of the contact parts are made of stainless steel. The actuator is separated from the actual valve. The slide valve opens and closes evenly from the centre, which makes it well-suited for dosing. The valve is equipped with the fixed conduction of the sealing plates and, if desired, with pneumatic control. This allows the sealing plates to be compressed in the closed position and to be relieved upon movement. The advantage: improved sealing of the sealing plates in the closed position and the reduction of wear at the opening and closing of plates.
 

 Casing

: Aluminium EN-AC 51100

 Inner material

: Stainless steel 1.4571

 Guiding

: Stainless steel 1.4408

 Seal materials

: PU, NBR, FPM, CSM, EPDM

 
 

Slide valve type FEP

 
Flat slide valve - A pneumatically controlled slide valve with elastic seal on the underside is pressed against the underside of the valve in the closed position. The slide valve is pressure-tight up to 5 bar. The valve does not come into contact with the fitting until closing, and so a light actuator will suffice. A threefold seating gland seals the valve from the inside.
